iPhone4/ iOS 7.1.2. No video when calling iPhone 10
When I FaceTime the latest iPhone they can see and hear me, I can only hear but not see them. The video does work with facebook messenger so I know there is nothing wrong with the camera. However this person will not do facebook so I can't use that.
Has anyone found a cause and a fix for this? Many thanks.
